Abstract

Abstract

Three kinds of ultrafine TATB with different microstructure were prepared, and 2% F2311 binder was added to make the TATB powder, and the TATB-based explosives were pressed with different densities. The influences of microstructure on the detonation-spreading performances of TATB-based explosives were studied by the modified floret test. The results show that the detonation-spreading performances are significantly influenced by TATB microstructures at the same short-duration shock initiation.
